The much touted 15-car train of the Western Railway (WR) will make its debut at Churchgate on Wednesday, Republic Day. The local train, which can accommodate 6,000 people during rush hour, had been on trial run between Dadar and Virar with halts at Bandra, Andheri and Borivli, and all stations between Borivli and Virar except Naigaon and Dahisar. On January 26, the service will be extended to WR’s southern terminus. After two-day tests, the service will be regularised on Friday. As with Dadar-Virar, there will be 12 Churchgate-Virar services daily by one train. But within the year, the number of trains would be increased to three, with the number of services going up to 50. Work to extend platforms three and four at Churchgate is almost complete.
